UNITED STATES hat WILLIAM C. HIERING, OF NEWARK, NEW JERSEY, ASSIGNR Tt)l'. Il. NEWARK, NEW JERSEY, A. CORPORATIN OF Dlilntiwllalt BAG LOCK.

Application led December This invention relates to fastening devices,more particularly as applied to bags, using the term generically, tohold two adjacent parts lirmly together along their' meeting edges.

One of the objects of the invention is to provide a hasp, hingedlyengaged on one of the members of the article to be secured, and carryinga spring actuated detent engageable 'with a lreeper lined on the matingmember of the article.

A further feature is in the provision of means by Which the detent maybe normally retracted and other7 lrey actuated means, co operativetherewith, to prevent retraction of the detent by the lirst named means,but which permits of engagement irrespective of the key actuated means.

Another aim is to produce means Whereby the hasp is normally raised outof engagement with the keeper.

It is a further purpose to provide a device composed of few and simpleparts, capable of economic production, readily assembled to produce aneat and attractive fastener susceptible of wide general application.

These and other important aims, objects and purposes are accomplished bythe novel construction, combination and arrangement of partshereinafter' described and shown in the accompanying drawing,constituting an essential portion of this disclosure, and in whichzmFigure 1 is a front elevational view of an embodiment of the invention,illustrating its application.

Referring in greater detail to the drawing, the numeral l0 designatesone of the inem-- bers of the bag or other article and lll the matingmember of the saine. Elu

The permanent, hinge ca V of the loch consif e to produce a hollenT casiabove the surface of the li reason of its cnclosimr rml project prongslil, aoapted to pass the Wall l() and al o a thin il forcing plate l5,if the n yielding yiiliablc nature, the E ii'imwi bent tightly thereoverto afford a secure strip..

The shape of the casino' may be 'vari will and the manner o: securiiWall l0 is one of choiceJ not exactly as shown.

'lhe front por parallel and adjacent the edge or the is sheai'ed at theeinls and ciu l to i elongated central hinggge elem tially at its lovversi e to udn 17 of a flat spring, the main p( which is disposed AVwithinthe oasiu held firmly against the inner surface top HYall by prongs lllsliearod from the if Wall, in a manner lilre the e shag, A l

bent to impinge en the of the spring, as u i lli il; and

A liasp il() is forii'ied of sheet metal with down turned edges 2li, siimilar to the editeL` of the hinge casing and of the salue lu g theseedges reenforcingI the hasp and impro i ing its appearance.

The main portion of the hiusp is of uni-- form Width, blending into aWider base por-- t-ion, sheared at the niiddle and cil each side topresent tiro hiwi el i conforming with the clcmen thereto by a hinge pinElli iu. th i ner, and it is to be noted that the fr' "'i i 17 isarranged to operativey ci tral portion of the hasp, in fro. i of thehinge, acting to press the liasp out Ward or away frein the bag materialll, over Which it extends.

The forward, free, end of the liasp il@ contains a circular opening 24,the surrounding metal being drawn upward to form a short cone orcylinder 25, cut out on the side adjacent the hinge, as at 26, for apurpose which will presently appear.

Enterable into the cone 25 is the rounded circular head 27 of a keeperstud, the reduced stem'28 of which extends from a disc 29, looselyfitting the opening 24 and formed on a plate 30 held to the bag member11 by prongs 31 passing therethrough and clinched over a thinreenforeing plate 32 on the under side of the material.

The lock mechanism is contained in an oblong rectangular casing 33 oflesser width than the lever 20 and secured centrally on its free end byprongs 34, extending from the side Walls 35 of the casing, which jointhe .front and rear end walls 36 and 37 respectively, to ,constitute acomplete closure except for a key hole 38 in its cover portion.

Slidaloly mounted in the lock casing 33, against the inner surface ofits cover, and filling the space between its side walls 35, is a pushpiece 39 having a narrowed frontend 40`extending through an opening inthe front wall 36, this projection being smoothly finished to beoperated by the fingers in releasing the catch, as will be seen.

The projection 4() has at its sides square shoulders 41 that limit theoutward movement, of the push piece 39, which contains a centralelongated opening 42 into which the tube25 enters and also the head 27of the detent.

A recess 43 in the inner portion of the push piece separates the sameinto two forks 44, 45, both forks being reduced at their left hand sideedges to provide extensions 46, 47.

Disposed on the push piece are the downwardly flanged edges 48 of a flatbolt 49 having forwardly extending arms 50, spaced substantially inaccordance with the width of the opening 42, and into this space extendsa central forwardly projecting lug 51, concavely curved at the frontedge and rounded on its upper corner to make contact with the detenthead 27, below which it engages, when passed through the opening 26 inthe tube 25.

A pad 52 is bent at a right angle from the i rear edge, at the center ofthe bolt 49, to

contact with the casing cover 33, being movable in the recess 43 of thepush piece 39, and extending rearwardly from the Vpad is a lug 53,adapted to retain the notched end 54 of abent Hat spring 55 in operativeposition on the pad. f

rl`he opposite end of the semi-elliptical spring 55 bears againstI theinner surface of a channel shaped controller 56, movable transversely inthe rear portion of the casing, against'the wall 37 and is provided withtwo indentations 57, 58, either of which is engageable with aprotuberance 59 on the inner surface of the wall to hold the coutrollerin either of its adjusted positions as moved by a key GO insertedthrough the key hole 3S.

The lower wall of the controller 5G is shaped to present two forwardlyextending stops 61, 62, relatively wide and narrow, and so arranged thatwhen the controller is moved to one side of the casing as to permit thepush piece 39 to be pressed inwardly, as shown in Fig. 5, but when atthe opposite side of the casing the fork projections 4G, 47 make contactwith the stops (l2, (il preventing retraction of the push piece 39 butpermitting the bolt 49 to move inward ly against the gr :'-ure of thespring 55.

The upper wall of the controller 5G presents simiiar but longerforwardly extending arms 63, G4 having between them a space throughwhich the ward of the key G() may extend when entered, the ward beingcontactable with either arm of the controller by which it is moved byturning the key thereby iermitting the push piece to he pressed in orheld positively extended as in Fig. 6.

It is to be noted that the bolt 49 is at all times free to recede, as bymaking forcible contact with the detent head in closing the haspirrespective of the position of the controller, or by pressing the pushpiece 39 into the lock when the controller is in position toV allow thisto be donc, as in Fig. 6.

Thus itis possible, by proper use of the key to prevent entrance to thebag at will or to release it for actuation by the push piece, in whichcase the hasp is instantly raised by the spring 18 and retained untilthe hasp is pressed down and catch element 51 reengages with the detent.

From the foregoing it will be seen that a simple device for this purposehas been disclosedin the preferred form of its embodiment, but it is notdesired to restrict the details to the exact construction shown, itbeing obvious that changes, not involving the exercise of invention, maybe made without conflicting with the scope of the appended claims.
